Verdict

The call

The clearest difference is in-app purchases: Paperpile at none against LiquidText's 13. Paperpile also leads on review sentiment (72% vs 50%) and iOS requirement (12.0 vs 17.6). LiquidText's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (6.4K vs 129). On price, rating, ads and device support there is nothing between them.
